FIRELESS COOKER.

Application filed January 2, 1912.

To all whom it may concern:

Be it known that 1, WILLIAM E. CAMP- BELL, a subject of the King of Great Britain, residing at Detroit, county ofVVayne, State of Michigan, have invented a certain new and useful Improvements in Fireless Cookers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being bad to the accompanying drawings, which form a part of this specification.

This invention relates to fireless cookers and has for its object, means for holding the radiator in the cooking chamber and for handling the same, placing it in the chamber and removing it from the chamber.

Heretofore, in fireless cooker practice, it has been the custom to use racks either supported on standards within the cooking chamber or else upon annular flanges eX- tending out into the chamber. In order to secure various positions for the radiator, either a number of standards have been provided or a number of flanges have been used, upon which to rest the racks. These are manifestly disadvantageous for the reason that standards and racks are liable to become bent and crushed and they require additional care in washing and cleaning. do away with these complicated devices and supply a very simple contrivance by which the radiator may both be handled and sup ported; and by providing any number of supplemental hangers of varying lengths, I can hang the radiator any desired distance above the article being cooked and, thereby, secure just the desired heat. The supplemental hangers are of such simple construction that any number of them can be supplied at a minimum expense.

In the drawings :Figure 1, is a vertical section of a part of the cooker chamber showing the cover and the radiating stone in section. Fig. 2, is a similar view showing the supplemental hangers used in connection with my invention. Fig. 3, is an enlarged View of the bottom of the hanger key.

A, is a casing of a tireless cooker, provided with the proper packing to prevent the escape of heat.

B, is the cover which fits upon the casing A in a step-like fit so as to more surely prevent the escape of the heat. Below the cover B is the customary cover G that is used over Specification of Letters latent.

the heating chamber D. The cover C may be lifted by the handle E and there is depending from the center of the cover, a key hanger F adapted to engage through a key slot G of the radiator H. This radiator has a circular recess 1, below the key slot G. The cover may be turned with the handle E until the bar of the key hanger F is parallel with the run of the slot G and .it may then be dropped into the recess 1, and the handle being given a quarter of a turn, the key securely engages the radiator H.

When it is desired to hang the radiator lower in the chamber, a supplemental hook J may be hooked over the bar portion of the key hanger and engage within the key slot G in the same way as the key hanger does. Any number of these hooks of varying lengths may be provided so as to adjust the radiator with respect to the article being cooked in the bottom of the chamber. These supplemental hooks are formed of heavy twisted wire having an off-set loop 7' at the top which hooks over the bar of the key hanger F and the ends of the wire are twisted with the separate ends pointing directly away from each other, forming the bar portion 7' that is adapted to engage in the recess 1.

What I claim is 1. The combination with a heat-insulated receptacle comprising a casing provided with heat-insulating packing, a cover that acts as a closure for the heating chamber formed by the said casing and that is provided with a handle for removing it, a hanger depending from said cover and removable therewith, and a radiator provided with means wherewith the hanger may be detachably engaged to handle the radiator and support the same in the heating chamber, substantially as described.

2. The combination with a heat-insulated receptacle comprising a casing provided with heat-insulating packing, a cover that acts as a closure for the heating chamber formed by the said casing and that is provided with a handle for removing it, a hanger in the form of a key depending from said cover and removable therewith and a radiator provided with a circular recess opening at the top in a slot whereby the key hanger may be inserted through the slot and given a quarter turn to removably attach it to the radiator so that the radiator may be handled by the key and supported by the same in the heating chamber, subacts as a closure for the heating chamber formed by the said casing and that is provided with a handle for removing it, a hanger in the form of a key depending from saicl'cover and removable therewith, a radiator provided with a circular recess, opening at the top of the radiator in a slot, whereby the hanger may be inserted in the slot and turned a quarter of a turn to connect the same together and a may be supported at difi'erent heights in 2- the heating chamber to vary the heating effects, substantially as described.

In testimony whereof, I sign this specification in the presence of two witnesses.
